A number of iOS game publishers, including Gameloft and Electronic Arts, have dropped the prices of several games in honor of the upcoming holiday weekend. EA has slashed the prices of NBA Jam, The Sims 3, FIFA 11, Dead Space, and Need for Speed: Hot Pursuit to $0.99. Gameloft’s Dungeon Hunter 2 and Starfront Collision are also just $0.99, as is Adult Swim’s Robot Unicorn Attack. Trucks and Skulls Nitro and Cross Fingers are both free this weekend, and both Zen Bound and Zen Bound 2 are priced at $0.99. If you’re doing some traveling on your way to a BBQ and need a good way to pass the time, be sure to hit up the iTunes App Store to take advantage of the sales. Of all the titles above, we highly recommend giving both Dungeon Hunter 2 and NBA Jam a play-through.
